The purpose of this study was to determine the possible deleterious effects of e-cigarette vapor on osteoblast interaction with dental implant material. Osteoblasts were cultured onto Ti6Al4V titanium implant disks and were then exposed or not to whole cigarette smoke (CS) as well as to nicotine-rich (NR) or nicotine-free (NF) e-vapor for 15 or 30 min once a day during one, two, or three days, after which time various analyses were performed. Osteoblast growth on the titanium implant disks was found to be significantly (p < 0...

The objective of this article is to review topography of posterior superior alveolar artery (PSAA), and to present a case with visualization of a rare anatomic variation of PSAA. An electronic search was undertaken to identify articles about topography of PSAA in Medline, Embase and Google Scholar databases, published between January 1977 and December 2017. Two animal studies, 8 cadaver studies, 18 CBCT studies, and 2 review articles were found. The animal studies, cadaver studies and review articles were excluded because they were not about topography of PSAA...

The present study compared early dental implant failure rates between patients with and without orthodontic treatment before dental implantation. The data of adults who had undergone dental implantation between January 2007 and December 2016 were analyzed retrospectively. A total of 124 subjects with 255 teeth were divided into a treatment group (46 subjects, 85 teeth) consisting of patients who had undergone implant surgery after orthodontic treatment, and a control group with patients who had not undergone pre-implant orthodontic treatment...

To report retrospectively on the 12-years follow-up results of the treatment and rehabilitation of edentulous maxillae, applying extra-sinus zygomatic implants alone or in combination with intra-sinus zygomatic implants. We recruited 22 Patients with 35 zygomatic Brånemark System Implants; 24 implants in the standard Brånemark protocol through the sinus and 11 extra - sinus implants outside the sinus. Additionally, 147 regular implants were placed (Brånemark System, Straumann, Nobel Replace, SternGold). The minimum follow-up period was from 50 months to a maximum of 152 months...

A 36-year-old male patient diagnosed with severe chronic periodontitis was treated with novel surgery for his maxillary right lateral incisor. Preoperatively, a 3D printer was used to produce a photosensitive resin bony anatomy replica based on CBCT datasets. The patient's blood was centrifuged to obtain advanced platelet-rich fibrin (A-PRF) and Injected platelet-rich fibrin (I-PRF), which were mixed with Bio-Oss, and packed onto the 3D replica to form the ideal shape. The replica was then positioned at the planned sites without any change...

The aim of this cohort study was to investigate the relationship between crestal bone levels and crown-to-implant ratio of ultra-short implants, after functional loading. 60 patients with single or partial edentulism and alveolar bone atrophy were enrolled and treated between December 2009 and January 2016. Without using bone-grafting procedures, patients were rehabilitated with ultra-short implants characterized by a micro-rough surface and a 6-mm length. Clinical and anatomical crown-to-implant (C/I) ratios and crestal bone levels (CBL) were measured after a follow-up period ranging from 12 to 72 months; all peri-implant and prosthetic parameters were recorded...

Deficient bone volume, anatomical limitations, lack of available mesio-distal space, adjacent teeth angulations, and surgical errors may lead to placement of narrow diameter implants. In such a scenario; a functional and esthetic yet sustainable replacement of missing more than one tooth becomes quite challenging. This article describes the successful restoration of missing both mandibular central incisors on one, 3mm single piece implant in three patients. Despite being a biomechanically complex presentation, the objectives of optimal outcome were achieved in all three patients by means of innovative designing, fine control of occlusal factors, and the correct choice of restorative material...

The mechanisms of early failures in dental implant osseointegration are unclear. A possible cause of low levels of bone formation is implant contamination with lubricants during insertion. To explore the impact of lubricant contamination on dental implants, we used five New Zealand rabbits and inserted two implants per tibia in each animal for a total of four implants per animal (20 implants in total). In general, bicorticalization was achieved. The first implant was placed as suggested by the manufacturer with no lubricant used (control)...

Dental implant therapy on patients with systemic diseases in conjunction with severely resorbed maxillary and mandibular bone present a challenge for dental rehabilitation. This case report describes the interdisciplinary comprehensive treatment completed on a patient with systemic lupus erythematosus (SLE) and common variable immunodeficiency (CVID). Patients with these systemic conditions present a multifactorial challenge for dental treatment due to advanced carious lesions, missing teeth, lack of adequate bone quality and quantity, in addition to the secondary effects of their medications...

The aim of this research letter was to report the results of a pilot study designed to compare the real and virtual position of implants placed using computer-guided flapless implant surgery for single restorations in the pre-maxilla. A total of 8 patients (2 men and 6 women) with a mean age of 40 years (32-73 years) had a total of 11 implants inserted using a tooth-supported stereolithographic guide. After implant placement, the positions (coronal, central, and apical) and angulation of the implants installed in relation to those planned were determined via the superposition of pre- and postoperative 3D models using Dental Slice software (Bioparts, Brasília, Brazil)...

The primary aim was to evaluate the association of patient related factors, biomaterials and implant characteristics on complications' rate of sinus graft surgery and on implant survival rate in grafted sinus. Secondary aims were to measure bone remodelling around implants and the patients' satisfaction. A retrospective cohort study was designed. Patients who had computer tomography before sinus surgery (T0), orthopantomography after implant surgery (T1) and at follow-up (T2), were included. Specific forms were used to collect clinical data...

The aim of this study was to measure and record the universal transmucosal abutment height, and evaluate whether it influenced loosening of the abutment screw, by analyzing the torque and detorque values after mechanical cycling. Thirty-six (36) implants, model CM Unitite (SIN), with internal conical connections (3.5 x 10mm) and respective universal prosthetic abutments (n=36, 3.25 x 6mm), were divided into three groups (n=12 each) with respective transmucosal heights of 0.8, 3.5 and 5.5mm. Insertion torque of 20Ncm was used in accordance with the manufacturer's specifications...

The primary objective of this study was to design the optimal geometry of a novel screwdriver; create the grooves on a ball head screw; and demonstrate its resistance to a torque of up to 40 Ncm at an angulation of 0, 15 and 30 degrees by using nonlinear finite element analysis. A secondary objective was to create a fool-proof and easily recognizable system. The grooved ball head screw and geometry of the screwdriver, functioning from an angulation of 0° to 30°, was generated using Pro-ENGINEER Wildfire 5...

In many cases, due to anatomical limitations, the placement of regular-length implants cannot be facilitated without the performance of advanced surgical procedures. However, these are associated with morbidity, prolonged treatment time, and costs. To overcome such disadvantages, short implants were introduced. The aim of this prospective pilot split-mouth study was to compare the clinical outcome between short implants (7 mm) and regular-length (≥10 mm) implants placed in the posterior mandible after 1 year of prosthetic delivery...

Achieving excellence in anterior rehabilitations requires close cooperation between the periodontist and the prosthodontist. Many techniques can be used to restore the lost alveolar hard and soft tissues. The more severe the peri-implant defect, the higher the challenge and lower the predictability of the procedure. The present case consists of Seibert Class III with malaligned implants in the esthetic zone resolved with a cost-modified treatment plan to reestablish esthetics in the anterior maxilla using a rotated palatal flap...
